The county economy is largely based on farming and cattle production. It is one of the top producing counties in the U.S. for wheat, cattle and hogs. It also lies within the noted Hugoton-Panhandle natural gas field.[2]

Texas County was formed at Oklahoma statehood (16 November 1907) from the central one-third of "Old Beaver County". When the formation of the county was authorized by the Constitutional Convention of 1907, the county was so named because it was wholly included within the limits of the Texas Cession of 1850, whereby the ownership of the area was passed from the State of Texas to the United States Government. From 1850 to 1890, its lands were never attached to any state or territory, never surveyed, and never divided into townships and sections like the eastern counties were. From 1890 to 1907, it was part of Beaver County.[2]

According to the U.S. Census Bureau, the county has a total area of 2,049 square miles (5,310 km2), of which 2,041 square miles (5,290 km2) is land and 7.4 square miles (19 km2) (0.4%) is water.[3] It is the second-largest county in Oklahoma by area. The county lies in the High Plains of the Great Plains physiographic region. It is generally flat, but has some rolling hills. It is drained by the North Canadian River, often called the Beaver River in this area. Tributaries of the river are Coldwater, Hackberry, Goff, Teepee, and Pony creeks.[2]

There were 7,153 households out of which 39.00% had children under the age of 18 living with them, 61.50% were married couples living together, 7.50% had a female householder with no husband present, and 26.60% were non-families. 21.20% of all households were made up of individuals and 8.20% had someone living alone who was 65 years of age or older. The average household size was 2.75 and the average family size was 3.19.

In the county, the population was spread out with 28.80% under the age of 18, 12.70% from 18 to 24, 29.10% from 25 to 44, 19.20% from 45 to 64, and 10.20% who were 65 years of age or older. The median age was 30 years. For every 100 females there were 105.90 males. For every 100 females age 18 and over, there were 106.90 males.

The median income for a household in the county was $35,872, and the median income for a family was $42,226. Males had a median income of $26,991 versus $20,404 for females. The per capita income for the county was $15,692. About 10.20% of families and 14.10% of the population were below the poverty line, including 17.80% of those under age 18 and 7.40% of those age 65 or over.

Cattle raising was the most important economic activity before and after statehood. Farming rose in importance after the 1890s. Despite the occurrence of the Dust Bowl these two sectors have recovered and prospered. By 1990, Texas County led the state in producing grain sorghums, with 4.2 million bushels, or one-quarter of the state's harvest, and was the state's fourth-largest wheat-producing county, harvesting 10.3 million bushels. By 1997 it was the state's top producer of both hogs and cattle.[2]

Petroleum exploration began in 1922 and resulted in natural gas production from the Hugoton-Panhandle Field. The county remains the nation's largest producer of natural gas. Four carbon-black plants operated near Optima from the mid-1930s through the 1940s.[2] The field extends from Hugoton, Kansas into the Texas Panhandle.

The Oklahoma Legislature created the Pan-Handle Agricultural Institute in 1909, offering secondary agricultural education for the Panhandle area. In 1921, the legislature changed the name to Panhandle Agricultural and Mechanical College and authorized the school to offer a two-year curriculum. In 1925, the State Board of Agriculture authorized upper division college courses, and in 1926, junior and senior level courses were added. The school name has been changed twice since then, to Oklahoma Panhandle State College of Agriculture and Applied Science (OPSU) in 1967 and to Oklahoma Panhandle State University in 1974.[13] The school is in Goodwell.
